We examined the effect of acetic acid feeding during exercise and ambient temperature after exercise on appetite and glycogen repletion in rats. Five‐week‐old male rats were provided meal twice daily and trained by treadmill run for 7d. On the 8th day, rats divided into 6 groups (n = 5) ran on treadmill at 30 m/min for 30min×4 sets. The rats were given oral gavage of 1.5 ml water (W) or a solution containing 300 mg/100 mL acetic acid (A) during a 10 min rest period allocated between 4 exercise sessions. After exercise, 5 rats given W or A during the exercise session were killed immediately, and the remaining groups were given a standard laboratory diet and water ad libitum for 1h under room temperature (R, 26°C) or cooling temperature (C, 20°C), respectively. These rats were killed at 4h after the start of feeding. The food intake was not statistically different among the groups, whereas AC was greater than the other groups (WR, 4.9 g (SD 2.8); WC, 4.7 (2.9); AR, 4.9 (2.0); AC, 7.0 (2.1)). The glycogen content in the liver and soleus muscle was greater in AC than the other groups (liver, WR, 23.6 mg/g tissue (9.2); WC, 25.0 (9.7); AR, 25.4 (5.9); AC, 35.0 (5.6); soleus, WR, 1.84 (1.1); WC, 1.95 (1.4); AR, 2.36 (1.6); AC, 3.08 (1.0)). These results suggest that combination of acetic acid feeding during exercise and feeding under cool temperature after exercise might enhance glycogen repletion in liver and skeletal muscle due to greater appetite after exercise.
